SLATE FASTENER.

Application filed. September 20, 1926', Serial No. 136,693, and in Norway September 29, 1924.

Hitherto it has been customary to aflix slate plates, shingles, and the like, asused forcovering roofs and house walls, to the roof battens or wall battens by means of nails, but thls means of connecting said parts with each other sufliers from the drawback that removing damaged single or individual slate plates etc. is either very ditfieult or impossible, except that a certain number of the undamaged plates etc. be removed, too. But just th1s gives rise to further damages, viz of previous ly undamaged plates etc., chiefly because of the necessity to remove the nails.

These drawbacks are obviated in and by my present invention which relates to a connecting and disconnectingmeans forthe battens and the individual plates etc. which now can be removed from, and attached to, the battens singly, and for this purpose I attach to every slate plate or shingle or the like a horizontal suspension member which extends over the entire breadth of the slate etc. and may be about hook-shaped in cross-section and serves for suspending the slate etc. from the respective batten. If any one of the thus suspended plates should break it can be removed quite easily at once, without any disturbance of the neighbouring plates etc., and a neWplate etc. may be substituted for the damaged one also very easily practically in a moment; besides, examining a roof or a wall entirely in order to ascertain the condition of the plates etc. can be eifected most conveniently in a perfectly, satisfying manner. A particular effect of the member aflixed to the slate plate etc. resides therein that it increases considerably the resistibility of the plate etc. whereby this latter is by far less subject to being damaged, in consequence whereof the number of the plates etc. requiring exchange is greatly diminished and the periods of time after which the respective roof or wall requires repairing are considerably extended.

Several constructional forms of the invention are illustrated diagrammatically and by way of example on the accompanying drawing on which Figure 1 is a bottom-view of the first i'orm thereof, Figure 2 a side-view of the middle part of the same, Figure 3 a separate View of the two hooks and their connecting ledges as pertaining to the slate-plate;

Figures 4P6 are views like those of Figs. 1-3,

but show a modification; Figure 7 is a perspective representation of fastening memhers corresponding to Figs. 13 and being drawn to an enlarged scale, Figure 8 showsa modification of these members and Figure 9 is a perspective illustration of four slateplates with their fastening lodges and combined with fastening members of the kind shown in Fig. 7 placed on twobattens and seen from the interior ofthe roof.

vention.

In the modification shown in Figs. 4-6 the ledge f is connected with thoselegs of the hooks c which contact with the slate-plate 7),

and the shape of the hooks differs slightly There is one pin from the shape of the hooksshown in Figs.

1-3, as shown. These hooks (of Figs. 1-3) are illustrated perspectively and on an en larged scale in Fig. Tseparately, i. e. detached;

from the slate-plate, but connected with one another by the ledge f, and the other hooks (of Figs. 44)) are also shown separately in Fig. 8, and Fig. 9 shows hooks and ledges of the kind shown in Fig.7 attachedto some slate plates 6 by the intermediary of wooden ledges cl which are supported by the battens g.

Iclaim: A slate fastening device, comprising, in

combination with the slate plate, a conneeu ing member comprising two coupling mem bers affixed to said plate, and a ledge conneeting them with each other, said connecting members being adapted to be attached detachably to a batten from which the saidplate is to be suspended, and means located at the ends of the said ledge and connecting it undetacln ably with the said plate.

In testimony whereof I aflix my signature.
